The Gatifloxacin – 5 μg Antibiotic Disc – Bioanalyse is a paper disc impregnated with 5 micrograms of gatifloxacin, a second-generation fluoroquinolone antibiotic. It is used in the disc diffusion method of antimicrobial susceptibility testing to determine the susceptibility of bacteria to gatifloxacin.

The disc diffusion method is a simple and inexpensive method for testing the susceptibility of bacteria to antibiotics. It is based on the principle that bacteria that are susceptible to an antibiotic will not be able to grow near the disc containing the antibiotic.

To perform the disc diffusion test, a bacterial suspension is spread on the surface of an agar plate. Antibiotic discs are then placed on the surface of the agar plate. The plates are incubated for 16-24 hours, and then the zones of inhibition around the discs are measured. The size of the zone of inhibition is proportional to the susceptibility of the bacteria to the antibiotic.

The Gatifloxacin – 5 μg Antibiotic Disc – Bioanalyse is a valuable tool for the diagnosis and treatment of a wide range of bacterial infections, including:

• Pneumonia
• Acute bronchitis
• Sinusitis
• Skin and soft tissue infections
• Urinary tract infections

Interpretation of results:

| Zone of inhibition | Interpretation | |—|—|—| | ≥ 21 mm | Susceptible | | 16-20 mm | Intermediate | | < 16 mm | Resistant |

It is important to note that the disc diffusion method is only a semi-quantitative method for testing the susceptibility of bacteria to antibiotics. For more accurate results, other methods such as broth microdilution or agar dilution should be used.

The Gatifloxacin – 5 μg Antibiotic Disc – Bioanalyse is a valuable tool for the diagnosis and treatment of a wide range of bacterial infections. However, it is important to be aware of the potential side effects of gatifloxacin before using it. Gatifloxacin can cause side effects such as nausea, vomiting, diarrhea, and rash. In rare cases, gatifloxacin can cause serious side effects such as seizures and tendonitis.

Limitations of the Gatifloxacin – 5 μg Antibiotic Disc – Bioanalyse:

• The disc diffusion method is only a semi-quantitative method for testing the susceptibility of bacteria to antibiotics. For more accurate results, other methods such as broth microdilution or agar dilution should be used.
• The disc diffusion method is not able to detect all bacteria that are resistant to gatifloxacin. For example, some strains of Pseudomonas aeruginosa are resistant to gatifloxacin, but they may not produce a zone of inhibition around a gatifloxacin disc.
• The disc diffusion method can be affected by the type of agar plate used, the incubation temperature, and the inoculum density. Therefore, it is important to follow standardized procedures when performing the disc diffusion test.

Additional information about gatifloxacin:

Gatifloxacin is a second-generation fluoroquinolone antibiotic. Fluoroquinolone antibiotics are effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. Gatifloxacin is a bactericidal antibiotic, which means that it kills bacteria.

Gatifloxacin is a safe and effective antibiotic for most people. However, it is important to be aware of the potential side effects of gatifloxacin before using it. Gatifloxacin is not recommended for people who are allergic to fluoroquinolone antibiotics or for people who have tendon problems.
